Your Child's Asthma: Flare-ups

What happens during a flare-up?

Children with asthma have severe episodes or flare-ups when the air passages in their lungs become narrower. This makes it harder to breathe. Sensitive airways react to certain things called triggers. Triggers can cause:

The lining of the airways (bronchial tubes) to become more inflamed and swollen

Tightening of the muscles that surround the airways

More mucus production

Less air movement through the lungs

Your child may have the following symptoms of a flare-up:

It may become harder to breathe. Your child may start breathing faster than normal. They may use muscles that they normally don't use to breathe. This will make it look like the area under or between the ribs is sucking in or the belly is sticking out.

Chest tightness

Coughing

Wheezing or whistling when breathing out. Wheezing may not happen with very severe flare-ups.

Symptoms that wake your child or keep them from sleeping

Trouble walking or talking

Make sure you know what to do if your child's symptoms get worse. Always have his or her asthma medicines and asthma action plan available to use in case of a flare-up. If your child does not get treatment right away during a flare-up, they could stop breathing, or even die.
